java - day14 - InnerClass

内部类使用

package com.InnerClass;

public class Mama {
    String name;
    Baby baby;
    Mama(String name){
        this.name = name;
        baby = new Baby();  //外部类创建内部类对象
        baby.mamaName();
    }
    Baby creat(){
        return new Baby();
    }


    class Baby{   //内部类
        void mamaName(){
            System.out.println(Mama.this.name);  //可以简写(name)
                                                 //如果写成(this.name)则不对,this指代对象不对
        }
    }
}
